Untreated effluents and raw sewage containing large solids are moved reliably through large-scale utility infrastructure.\u003c\/p\u003e\u003cp\u003eFlow capacity reaches 23880 L\/min with a maximum head of 25.5 m, powered by a 50 kW motor. The 8-pole motor operates at 726 rpm on a 415 V three-phase supply, drawing 98 Amps for consistent torque delivery during peak collection periods.\u003c\/p\u003e\u003cp\u003eA ductile iron 2-channel impeller with 105 mm solids passage prevents internal clogging by allowing large particles and organic contaminants to pass safely. The optimized flow path maintains steady circulation even with highly contaminated wastewater.\u003c\/p\u003e\u003cp\u003eDuctile cast iron construction with IP68 enclosure and Class F insulation provides maximum submerged durability. SiC\/SiC shaft seals and integrated moisture sensors protect against liquid ingress.
